As a first analysis, we can try to answer the question by means of a nonparametric data analysis, without assuming any theoretical model.
Stat > Reliability/Survival > Distribution Analysis (Right Censoring) > Nonparametric Distribution Analysis
We can determine the reliability after 17 500 copies looking at the row in bold face in the previous table. At 13 471 copies the reliability is 0.3714. No other toner fails until 17 500 copies and therefore, the empirical reliability at 17 500 copies is 0.3714.
We will now check which theoretical models best fit our data:
Stat > Reliability/Survival > Distribution Analysis (Right Censoring) > Distribution ID Plot
In this case, our data approximately form a straight ...
